Abstract: A spatially and mechanically independent removable display attachment with wedge retainers for vertical cylindrical supports which consists of a flat member surrounded by an upwardly rising rim and an upwardly protruding open tubular segment. The opening completely pierces the flat member, so that a pole or pipe can easily slide through the invention. The attachment is supported at various vertical distances along the pole by a combination of structural innovations, O-rings, and in intimate physical contact and combination with wedgelike retainers.

Abstract: A planter box for installation on the top of a narrow horizontal surface includes a lower surface with at least one recessed depression. Each depression comprises serrations around its periphery. A rectangular connector with serrations complementary to the serrations of a respective depression and a downwardly depending peg, is frictionally inserted in each depression. In this manner, when the box rests on the top of the panel, one peg extends downwardly in close relation, but not contacting the panel. A wedge member is provided for each peg, each wedge member including a block with a friction surface to contact a respective wall member side, and a slanted slot to receive a respective peg. As each wedge member slides along a respective peg in a direction parallel to the panel top, the friction surface of each wedge member will be brought into frictional contact with a respective panel side to hold the planter box in place.

Abstract: A planter box for installation on the top of a narrow horizontal surface such as the top of a movable room partition or panel includes a lower surface with at least one pair of side-by-side, circular depressions. Each depression includes serrations around its periphery. A rectangular connector with serrations complementary to the serrations of a respective depression at its short ends, and a downwardly depending peg, is frictionally inserted in each depression at an angle such that, when the box rests on the top of the panel, one peg extends downwardly on each side of the panel in close relation, but not contacting the panel.

Abstract: A spatially and mechanically independent donut bowl structure is provided. The preferred embodiment consists of a flat member surrounded by an upwardly rising rim and an upwardly protruding open tubular segment on the upper surface. The opening completely pierces the donut bowl, so that a pole or pipe can easily slide through the invention. The donut support can be used by itself as a small dish. It can also be used interchangeably as a versatile, lightweight, and inexpensive container or tray component to any variety of decorative displays using poles, pipes, or pedestals.
